Group health care refers to a health insurance plan that covers a group of individuals, typically employees of a company or members of an organization. This type of coverage often provides access to a range of medical services and treatments at a reduced cost compared to individual health insurance plans. Group health care plans are usually offered by employers as part of an employee benefits package, and they can help spread the risk and cost of medical care among a larger pool of people, often resulting in lower premiums and out-of-pocket expenses for participants.
